Well this is a tricky one. I'm going to start with the easy... That is to say how you know if you are in love with him. A general tell as to if you are in love is if 80% of the time you are thinking about the guy in question. (What is he doing right now?) (What is he doing this weekend?) (What class is he in right now?) (I wonder if I will see him in the hall?) Things like that. Some people say that you don't need to be attracted to someone to be in love. This is not true you can love someone that you are not attracted to but you can't be IN LOVE with a person you are not attracted to them. I like a girl and I personally can't see flaws with her I'm sure she has them but I don't see them. OK... now for the hard part. How to tell if he loves you. Just because a guy is checking you out or just because he is nervous around you does not me that he is in love with you. One tell is if when you make eye contact he smiles. (Side note... don't stare at him till he sees you its just weird.) Another tell is if he is trying to initiate interaction between you and him such as a conversation. Or he may be trying to do the same things as you. Yet another tell would be if he is polite and try's to put you before himself. (If it is cold out and he has a jacket he may offer it to you.) < that is not always a sure thing because a lot of the time people will be nervous because they think that is cheesy. I hope this helps I myself am very shy so this stuff is hard for me but I know it to be true and it should work for you. :D
affection
it is a strong thing to now if someone loves you it is caused by your fellings and if you love them they will love you
Your question is contradictory. "What if you love someone and she loves you back but she doesn't?" ...Clearly the answer would be that she doesn't really love you, and you know this, as you stated "but she doesn't."
If someone loves you all they want to do is be around you and talk to you constantly. They will do anything to make you happy.
When you're in love you feel so good because you know that someone loves you. And you know that you love someone so you're not lonely and desperate.
True. There is no questioning it. You know it through and through.
talk to Them
If someone you loves says I love you, you reply as I love you too...! but if its someone else...you should let the person know about what you feel about him/her.. p
just tell them
You really can't base whether or not someone loves you just by them saying it. She has to be able to show you. If she is respectful of your feelings, supportive, and able to communicate with you how she feels then she loves you.
wow that is a tough one all you can do is tell him how you feel. if that someone is angry with you tell them to back off because he loves you and not the other person
you don't know but your heart will know..you can feel it if that someone loves you...just because someone tells you they love you over a thousand times doesn't always mean they love you...but if someone loves you they will show it to you without speaking a word.
